IRIX is a UNIX based OS written by SGI for their workstation computers.
SGI workstations are extremely high end graphics processing machines commonly
used for 3D animation, visual simulations, and many scientific applications.

This is the default IRIX desktop.

The menu in the upper left is the Toolchest. This menu is normally present
on the desktop and provides a list of the applications and utilities that
are installed on the system.

The camera and mic icons launch applications used for video and audio
capture. Most Silicon Graphics workstations come with a video capture device,
generally a camera.

The personal data folder (or "home" folder) for the current user also
displays on the desktop. In this case the user is "root".

The dumpster is used to delete files by dragging and dropping their
icons to it. This is basically the same as the Windows "Recycle Bin" and
the Macintosh "Trash" icon.

CDROM - A starting point for browsing the files on the CD-Rom media.
Other attached media drives will also appear on the desktop when connected.

Minimized applications appear as a square icon on the screen such as
this Netscape icon. The application running in the above screen shot (and
shown in the other screen shots) is The Gimp, a popular graphics program
used to make these screen shots.

This screen shot shows System Manager, the central system configuration
utility / control panel. It provides for easy configuration of hardware
devices, user accounts, and networking.

This screen shot shows a Directory View window which is used for managing
files. The pain at the bottom is the Content Viewer pane that can preview
different file types. This screen shots shows the Content Viewer previewing
a graphic.

In the File View window the roller on the left side of the window is
used to change the size of the icons.

One of the most unique features about the IRIX desktop is that its
icons are vector images instead of bit-mapped images. This means they can
scale to any size in real-time without losing any quality.

Like many other Unix desktops IRIX has the ability to work with multiple
desktops at once. Switching and managing these desktops is accomplished
through the Desktop Overview

This screen shots also shows the audio panel and the included SGI branded
version of Netscape Navigator.
